“…(2.4–19.9% in the suburban samples and 0.1–1.5% in the high-altitude samples; 5.4% on average) (Table S4). Although Cladosporium is generally considered the most common outdoor genus in temperate climates (Gonçalves et al, 2010; Núñez et al, 2016; Lin et al, 2018), this fungus was only detected in low percentages from the high-altitude sites. In addition, the two different trajectories for each site were similar on each sampling day except August 27, 2011.…”

“…In addition, the two different trajectories for each site were similar on each sampling day except August 27, 2011. The main cause may be related to vegetation type and weather conditions (Awad, 2005; Lin et al, 2018). Therefore, these findings suggest that the influence of local environmental factors on the airborne eukaryotic community are more important than those on the airborne bacterial community.…”

Airborne microorganisms, especially those at high altitude, are exposed to hostile conditions, including ultraviolet (UV) radiation, desiccation, and low temperatures. This study was conducted to compare the composition and abundance of airborne microorganisms at a high-altitude site, Mt. Jodo [2,839 m above mean sea level (AMSL)] and a suburban site (23 m AMSL) in Toyama, Japan. To our knowledge, this is the first study to investigate microbial communities in air samples collected simultaneously at two sites in relatively close proximity, from low and high altitude. Air samples were collected over a period of 3 years during 2009–2011. We then examined the bacterial and eukaryotic communities and estimated the abundance of bacteria and fungi with real-time TaqMan PCR. The airborne bacterial and eukaryotic communities differed between high-altitude and suburban sites on each sampling day. Backward trajectory analysis of air masses that arrived at high-altitude and suburban sites on each sampling day displayed almost the same paths. The bacterial communities were dominated by Actinobacteria, Firmicutes, and Proteobacteria, while the eukaryotic communities included Ascomycota, Basidiomycota, and Streptophyta. We also predicted some application of such microbial communities. The airborne bacterial and fungal abundance at the high-altitude site was about two times lower than that at the suburban site. These results showed that each airborne microbial communities have locality even if they are collected close location.

“…There is also ambiguity regarding the concentration of fungal spores. While certain studies highlight an increase in fungal spore concentration close to rural areas (Lin et al 2018;Di Filippo et al 2013;Oliveira et al 2009Oliveira et al , 2010Kaarakainen et al 2008;Kasprzyk and Worek 2006), others see an enhancement in urban environments (Rathnayake et al 2016;Bauer et al 2008;Pei-Chih, Huey-Jen, and Chia-Yin 2000). Overall, it seems that the relationship between land use and bioaerosols is not well understood and the effect of meteorological factors, season, and the local environment on the airborne community assembly still needs to be determined (Liu et…”

Outdoor field measurements of bioaerosols are performed within a wide range of basic and applied scientific disciplines, each with its own goals, assumptions, and terminology. This article contains brief reviews of outdoor field bioaerosol research from these diverse interests, with emphasis on perspectives from the atmospheric sciences. The focus is on a high-level discussion of pressing scientific questions, grand challenges, and needs for cross-disciplinary collaboration. The research topics, in which bioaerosol field measurement is important, include (i) atmospheric physics, clouds, climate, and hydrological cycle; (ii) atmospheric chemistry; (iii) airborne allergencontaining particles; (iv) airborne human pathogens and national security; (v) airborne livestock and crop pathogens; and (vi) biogeography and biodiversity. We concisely review bioaerosol impacts and discuss properties that distinguish bioaerosols from abiological aerosols. We give extra focus to regions of specific interest, i.e., forests, polar regions, marine and coastal environments, deserts, urban and rural areas, and summarize key considerations related to bioaerosol measurements, such as of fluxes, of long-range transport, and of sampling from both stationary and vessel-driven platforms. Keeping in mind a series of key scientific questions posed within the diverse communities, we suggest that pressing scientific questions include the following: (i) emission sources and flux estimates; (ii) spatial distribution; (iii) changes in distribution; (iv) atmospheric aging; (v) metabolic activity; (vi) urbanization of allergies; (vii) transport of human pathogens; and (viii) climate-relevant properties.

“…As an effort of understanding ambient bioaerosols, Emygdio, Degobbi, Gonçalves, and Andrade (2018) reported fungal spore concentration levels in Brazil and found the highest concentration up to 23,780 spores/m³ in autumn and typically the concentration was found to be the highest at the dawn. On the other hand, Lin et al (2018) showed that the spore concentration levels depended the urbanization, and they also found that urban and rural areas had significantly different airborne fungal floras and spore concentration. Recently, there is an increased interests in studying bioaerosol dynamics during the haze events (Wei et al, 2016).…”

Bioaerosol collectively refers to all suspended particles of biological origins in the air. In theory, all biological materials can be released either directly or resuspension into the air upon various disturbances from the earth surfaces such as soils, oceans, animals, forests, humans and etc. Once airborne, as shown in Fig. 1 biaoerosol particles could undergo human inhalation, dry/wet depositions, aerial transport, ice nucleation, cloud condensation processes, atmospheric transformation and others. Accordingly, they have important impacts on infectious disease spread, allergic diseases, bio-security, atmospheric chemistry as well as climate (Douwes et al.,
